To ('ZZ iff/71.0722 t muy concern Be it known that I, Cr-rAnLns R. KLrNn, a citizen of 'the United States, residing at Reading, county of Berks, State of Pennsylvania, haveinvented a new and useful Furnace and Boiler Casing, of which the following is a. specification.

My invention consists of a norel construction of a casing for furnaces, vapor,wat'er, steam and other boilers, and comprises an outer casing of metal sheets builtiny sections whose meeting edges are locked in a novel manner, said sheets having an internal lining of asbestos or other suitable heat resisting material, which entirely encloses 'the boiler, said casing having openings aligning with insulated boiler or furnace doorsand ensuring a dead air space between the actual surface of the boiler and the outer casing, thereby insuring perfect insulation and a marked saving in fuelconsumed.k

lt further consists of other novel features of construction, all as will be hereinafterA fully set forth.

For the purpose of illustrating my invention, I have shown in the accompanying` drawings a form thereof which is at present preferred by me, since it will givein practice satisfactory and reliable results, although it is to be understood that the various instrumentalities of which my invention consists can be variously arranged and organized and that my invention is not limited to the precise arrangement and organization of these instrumentalities as herein shown and described. n

Figure 1 represents a vertical sectional view of a furnace and boiler casing embodying` my invention.

Figure 2 represents on an enlarged scale a sec-tional View of the right-hand portion of Figure 1.

Figure 3 represents a front elevation of Figure 2.

In carrying out my invention I provide an outer sectional casing composed of the' front 2, the top 41, and rear and end walls, the casing sections being of metalor in the form of metal sheets as sheet-iron'and pro-- vided with an internal lining 5 of asbestosy or other suitable lheat resisting kmaterials whereby a sectional casing is provided which entirely encloses the boiler or the like, whereby a dead air space is insured between the surface of the boiler and the outer casing, thereby insuring perfect insulation and a marked saving in fuel consumption.r` The juxtaposed meeting ends of the sections as seen at the top of'Figure 1 arer provided ywith .flanges deflected therefrom at a right angle and provided withloclring members composed of 'thev body porti-on 13 and the inwardly converging 'wallsllh In Figures 1 ,and 2, Iy have sho-wn the boiler 19 as provided'with` the nonconducting covering 2O and with ythe front water leg 21 having the firing opening 22, which y `is accessible through'the firing door 23, it

being apparent that the latter is 'interiorly lined with non-conducting material, as indicatedat 23X, and that the outwardly projecting flange 22X, which surrounds the firing opening 22, projects voutwardly to such anv extent that it is embedded in the lining 231 when the yfiring door-is closed, softhata tight joint isy effectedpwhen Vsaid Adoor 'is closed. The casing front 2 has an opening lining 26. It will be further apparent that,

said casing door 25 is enough larger than the casing aperturey 22 to provide, when closed, a margin of insulating material shutting tightly on the outside or face ofthe casing thus interposing a strip of insulation between the meta-l of the casing door and the metal of the casing thereby destroying the heat conductivity of the metals, it being apparent that'said casing door is held in closed position by the handle 27, it being apparent that I have provided my novel casing with a door 25, in alignment with the firing door 28 of the boiler, and that said casing door when closed effectively seals the casing opening formed/by the internal fiange 24.

It will be apparent from Figures 1 and 2 that by providing the outer casing of metal terial, which entirely incloses the boiler, and

ythat the same forms in effect a continuation of the'casing and the lining 5.

It will now be apparent that I have devised a novel and useful casing for a furnace and steam, vapor and Water boiler which embodies the features of advantage 'enumerated as desirable in the statement of the invention and the above description, and While I have, in the present instance, sho-Wn and described a preferred embodiment thereof Which Will give in practice satisfactory and reliable results, it is to be understood that the same is susceptible of modification in various particulars Without departing` from the spirit or scope of the invention or sacrificingpany of its advantages.

Having thus described my invention, what I claim as new and desire to secure by Let -terial and the inner surface of said boiler door being also provided With a liningof non-conducting material, and an outer pro- `iecting member surrounding the opening into said boiler, said member being adapted to be embedded in the non-conducting material of said'boiler door when the door is closed.

2. In a device of the character' stated, a casing for boilers or furnaces composed of metal sheets interiorly lined with non-conducting material, a. dooropening in one of said casing sheets formed by a deflected flange of said casing, a casing door hinged to said sheet in proximity'to said opening, a lining of non-conducting material on the inner surface of said casing door, said casing door being larger than the casing aperture so as to provide when closed a margin of insulating material abutting tightly on the face of said casing, thus interposing a strip of insulatingv material between the metal of the casing door and the metal of the casing, a door opening for a door Within said casing and in alignment With the casing (door, a flange secured to said latter door opening and having a laterally projecting portion, and non-conducting material attached to the inner face of the inner door and adapted to'be embedded in said flange when the inner door is closed. f
